It also records four new timing phases, meaning named steps whose duration is measured, at startup or at the start of a turn:\n\n- `message_prep`\n\n- `model_config_wait`\n\n- `auto_mode_context_wait`\n\n- `model_client_data_wait`\n\n**Why**\n\nThe timing phases show in more detail where the wait before a turn is spent. The new error type gives a separate name to a failure involving removed media.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
